Sorry to go off-topic, but just out of curiosity, are you only doing Wing Chun at present, or are you studying any committed grappling styles?

Since this is YMAS I'll briefly address that. Yes, I also train MMA as well. Wing chun is my primary striking style. I seem to favor Folkstyle wrestling and Sambo more than BJJ, but my most experience is ironically in BJJ. I just don't do as well with submitting as I do taking down and controlling people.

Having said that one of the things I've been working on the last few months is my inverted shot to heel hook or ankle lock. TO many this looks very similar to a Ryan Hall style inverted guard entry and not applicable for mma, however, if the person doing it is of high enough skill....
